| 5 | New font handling mechanism with font backend method | |
| 6 | ---------------------------------------------------- | |

8 | The new files are: |
| 9 | font.h -- header providing font-backend related structures | |
| 10 | (most important ones are "struct font" and "struct | |
| 11 | font_driver"), macros, and etc. | |
| 12 | font.c -- main font handling code. | |
| 13 | xfont.c -- font-driver on X for X core fonts. | |
| 14 | ftfont.c -- generic font-driver for FreeType fonts providing | |
| 15 | device-independent methods of struct font_driver. | |
| 16 | xftfont.c -- font-driver on X using Xft for FreeType fonts | |
| 17 | utilizing methods provided by ftfont.c. | |
| 18 | ftxfont.c -- font-driver on X directly using FreeType fonts | |
| 19 | utilizing methods provided by ftfont.c. | |
| 20 | w32font.c -- font driver on w32 using Windows native fonts, | |
| 21 | corresponding to xfont.c | |
| 42a835e5 JR |
22 | w32uniscribe.c -- font driver on w32, using the uniscribe API |
| 23 | to provide complex script support for opentype fonts on | |
| 24 | Windows 2000 and later, or earlier versions of Windows | |
| 25 | with uniscribe installed as an add-on. | |

27 | So we already have codes for X and w32. For Mac it seems that we need |
| 28 | these files: | |
| e88a2ed3 GM |
29 | atmfont.c -- font-driver on mac using ATM fonts, corresponding |
| 30 | to xfont.c | |
| 31 | As BDF fonts are currently used on w32, we may also implement these: | |
| 32 | bdffont.c -- generic font-driver for BDF fonts, corresponding to | |
| 33 | ftfont.c | |
| 34 | bdfw32font.c -- font-driver on w32 using BDF fonts, | |
| 35 | corresponding to ftxfont.c | |
| 36 | But, as FreeType already supports BDF fonts, if FreeType and | |
| 37 | Fontconfig are also available on w32, what we need may be: | |
| 38 | ftw32font.c -- font-driver on w32 directly using FreeType fonts | |
| 39 | utilizing methods provided by ftfont.c. | |

41 | It may be interesting if Emacs supports a frame buffer directly and |
| 42 | has these font driver. | |
| 43 | ftfbfont.c -- font-driver on FB for FreeType fonts. | |
| 44 | bdffbfont.c -- font-driver on FB for BDF fonts. | |
| 45 | ||
| 46 | Note: The fontset related codes are not yet matured to work well with | |
| 47 | the font backend method. So, for instance, even if you start Emacs | |
| 48 | as something like this: | |
| 49 | % emacs -fn tahoma | |
| 50 | Non-ASCII Latin characters will not be displayed by the font "tahoma". | |
| 51 | In such a case, please try this: | |
| 52 | ||
| 53 | (set-fontset-font "fontset-default" 'latin '("tahoma" . "unicode-bmp")) | |
